Iyo abajenjeri bagaragaje ibyuma bisobanutse neza kubikoresho bya hydraulic, amazu ya pompe, cyangwa shitingi ya winch - cyane cyane mumuvuduko mwinshi, kwambara cyane, cyangwa kwangirika - ntibakenera uwabitanze gusa. Bakeneye a kwigana uruganda rwicyuma ibyo byumva imyitwarire ya metallurgjiya, ituze ryurwego, nuburyo bwo kunanirwa imikorere - ntabwo kwihanganira gushushanya gusa.
Twabonye imishinga myinshi ihagaze kuri prototype kuko uruganda rwatoranijwe rwafashe MIM nk "ubundi buryo bwo kubumba." Mubyukuri, MIM igenda neza kubice byingenzi byingenzi bisaba guhuza cyane hagati yo gutoranya ifu, guhuza binder, gutesha agaciro kinetics, kugenzura umwirondoro, no gutunganya ibicuruzwa. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dufata buri gice cya MIM nkicyicaro cya cobalt-nikel alloy valve intebe: ikosa rimwe mugucunga karubone mugihe cyo gucumura rishobora gukurura microcracking munsi ya bar-300 zipakurura cycle. Niyo mpamvu ikigo cyacu cyujuje ISO muri Qingdao kidatanga inguzanyo cyangwa gucumura-dufite ibyuzuye byuzuye byumuriro, kuva kuri 650 ° C ya catalitike ya 1250 ° C gucumura icyuho hamwe no kugenzura neza ikime.
Abaguzi benshi birengagiza imbogamizi zikomeye: MIM irusha izindi net-imiterere-ariko gusa mu mbibi zikomeye za geometrike. Umubyimba wurukuta ugomba kuguma hagati ya mm 1,5 na mm 8. Ibipimo byerekana hejuru ya 6: 1 gradients. Amashanyarazi? Birashoboka - ariko gusa hamwe nibishobora kugwa ceramic cores, ntabwo ibikoresho bisanzwe. Twafashije abakiriya kongera gushushanya AMS 5387 cobalt alloy pompe ibice kugirango ikureho radiyo yimbere ikarishye, igabanya kugoreka icyaha 40% mugihe dukomeza ubunyangamugayo-inzira. Ibyo ntabwo ari theoretical. Nibibaho iyo ibyawe kwigana uruganda rwicyuma ikoresha ubufindo bwa MIM 120+ ku mwaka ku byokurya byo mu kirere-kandi ikandika buri gipimo cyo kugabanuka, icyerekezo cyintambara, no gutandukana kwinshi kuri buri cyiciro.
Dore itandukaniro MIM itomoye nibicuruzwa MIM:
- Gukurikirana ibikoresho bitangira mbere yuko ifu yinjira muri hopper.
- Gutanga inguzanyo ntabwo byateganijwe-birakurikiranwa: Aho kugirango ushire igihe kirekire, dukurikirana igihombo nyacyo-dukoresheje sensor ya gravimetric. A 0.3% isigaye ihuza itera umwirondoro wihuse - kuko gukuraho bituzuye bitera kubyimba; kurenza urugero gutumira guturika.
- Umwirondoro wo gucapa ni igice cyihariye, ntabwo ari itanura: Inzu ya pisitori ya piston ibona umuvuduko mwinshi unyuze kuri 800-1000 ° C ugereranije nozzle yoroheje. Duhindura ibihe byo gutura dushingiye kumashanyarazi yubushyuhe-ntabwo ari igishushanyo mbonera.
- Post-sinter geometrie ntishobora kuganirwaho: Buri gice cya MIM gikorerwa ubugenzuzi bwa CMM kurwanya GD&T guhamagarwa - ntabwo ari ibipimo gusa. Dupima uburinganire hejuru yikimenyetso kuri ± 1,2 µm, silindrike ku binyamakuru bya shaft kugeza kuri 0.8 µm, hamwe no gukomera (Ra) kumuhanda utemba ujya kuri .4 0.4 µm - byagenzuwe na optique ya profilometrie.
Bamwe bashobora kuvuga ko gutunganya CNC bitanga ukuri neza kuruta MIM. Nukuri - kuri geometrike yoroshye. Ariko gerageza ufate ± 0,015 mm yibanze kuri bore eshanu za coaxial muri fondasiyo imwe ya 316L idafite ibyuma, buri kimwe gifite insinga zimbere hamwe nicyambu cyo gusiga amavuta. Gukora icyo gice bisaba ibice bitandatu, impinduka eshatu, kandi byanze bikunze gutwarwa nubushyuhe. MIM verisiyo? Igice kimwe cyicyatsi, icyuma kimwe, igikorwa cyo kurangiza-na 22% munsi yikiguzi cyose mububiko buri hejuru ya 500 pc / umwaka. Turabigaragaza: igihembwe gishize, twatanze 1,200 T800 alloy center shaft rollers ya sisitemu yimodoka ya injeniyeri. Bose batsinze ibizamini 100% bikora kuri 18.500 N imbaraga za axial-zero rework.
Ibyo kwizerwa biva muburyo bwo guhuza ushobora kugenzura. Ikigo cyacu ntikibamo imashini ya MIM gusa n’itanura rya sinteri - ariko kandi ifite ibigo bya CNC byuzuye bishobora guhindura ibice bya CoCr byacumuye cyane kuri 85 HRC, itanura ryogukoresha ubushyuhe ryashyizwe kuri ± 2 ° C, hamwe numurongo wa passivasi uhuye na ASTM A967. Iyo umukiriya yohereje igishushanyo cya AMS 5387 icomekaho imyobo ihumye kandi ifunze kashe, ntitubaza ngo "Urashobora kubikora?" Turabaza: "Ni ubuhe buryo bukabije bwo guhangayikishwa cyane? Ni ubuhe buzima buteganijwe mu buzima? Ni ubuhe buryo bwo gutsindwa butuma uba maso?" Noneho duhitamo ibyokurya byiza, twigana kugoreka ibicumuro byongeweho, twubake ifu hamwe nicyuma cya H13 cyanone hamwe numuyoboro ukonjesha uhuza, hanyuma ufunge ibipimo byerekana mbere yo kurasa bwa mbere.
Niba urimo gusuzuma a kwigana uruganda rwicyuma, simbuka udutabo twinshi. Baza: Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Izo nyandiko ntizifunzwe muri kabili ya dosiye. Bifatanije na PO yose, ivugururwa mugihe nyacyo, kandi basangiye mbere yo kwemeza ibikoresho. Kuberako ibisobanuro ntabwo ari ishami. Nibisanzwe.
